Research output: Chapter in Book/Report/Conference proceedingConference contribution


For the realtime detection of atmospheric CH2O with ultra high sensitivity and excellent selectivity, a cw tunable mid-IR spectroscopic source based on difference frequency generation (DFG) was developed. Formaldehyde was used as an intermediate in testing the current understanding of hydrocarbon photochemistry. This instrument was used both at NCAR in Boulder and at a rooftop location at Rice University in Houston, TX to acquire high quality CH2O concentration measurement at the 1-20 ppbv level.
